Let's divide 9662819 by 840
The aim is to understand the frequency of 840 in 9662819.

On to step 1:
840 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 840

Let's proceed to step 2:
If we divide 96 by 840, we get 0 and a remainder of 96.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 96 after subtracting 0 from 96.
Append the next digit (6) from the dividend to 96 and continue with: 966 / 840

Moving on to step 3:
840 can be fit into 966 1 times, resulting in a remainder of 126.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 126 after subtracting 840 from 966.
Bring next digit (2) of the dividend behind the 126 and repeat the process: 1262 / 840

Step 4:
If we divide 1262 by 840, we get 1 and a remainder of 422.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 840 from 1262 leaves us with 422.
Fetch the next digit (8) from the dividend, attach it to 422 and continue: 4228 / 840

Going ahead to step 5:
4228 divided by 840 is 5 with a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
If we take 4200 away from 4228, we end up with 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 840

On to step 6:
281 divided by 840 is 0 with a remainder of 281.
Use 0 as the next digit of our solution. 
Result so far: 1150.0
Deduct 0 from 281 and we're left with 281.
Include the next digit (9) from the dividend after 281, then repeat: 2819 / 840

Advancing to step 7:
The number 840 fits into 2819 3 times, leaving a remainder of 299.
Use 3 as the next digit of our solution. 
Result so far: 11503.0
Deduct 2520 from 2819 and we're left with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Going ahead to step 8:
The number 840 fits into 2990 3 times, leaving a remainder of 470.
Use 3 as the next digit of our solution. 
Result so far: 11503.3
Subtracting 2520 from 2990 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 9:
When dividing 4700 by 840, we get 5 with a remainder of 500.
Put 5 as the next digit of the answer. 
Result so far: 11503.35
Subtract 4200 from 4700 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 10:
If we divide 5000 by 840, we get 5 and a remainder of 800.
Use 5 as the next digit of our solution. 
Result so far: 11503.355
Subtracting 4200 from 5000 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The quotient of the division is 11503.355, and the remainder is 0.08.
